Bug in formatting of numbers in thermal simulation

I was messing around and learning with thermal simulation and noticed at one point that formatting of temperature values doesn't handle the extreme values well, e.g., reporting the max temperature as 117 C and the minimum temperature as 457.8 C, which is obviously wrong. The problem has to do with how the formatting is not handling numbers using scientific notation. It's an extreme condition given the temperature ranges involved, but still something like formatting of numbers for accurate presentation is something that should be pretty standard.

Although the extreme condition used to generate this are not realistic in any real world application, something as simple as typo or entering by mistake the wrong value for a heat source can produce the results in the simulation. If one were dealing with a complicated design and under pressure to hit a deadline, it's easy to see that the unrealistic results wouldn't be noticed (117C and 457.8 C are realistic values in some applications) and error might go undetected.

Hi @phovmand,

Could you share the study setup with us?  I see scientific notation used for high values in the legend + min/max labels.

 

The unit and value display can be controlled via user preferences.  You may be able to see the real values by turning off the scientific notation display.

It's logged in our system now as FUS-51864, and will be forwarded on to Development once we have a reproducible case.

Thank you for reporting this.

Best regards,

Hi Peter,

We are still looking for a dataset that reproduces this issue. Please see if Hugh's suggestion works for you. Without the dataset I'm afraid we will end up closing this issue. Thanks

 

Best regards
